LEO VON TRESCKOW, OF NEW ORLEANS, LOUISIANA.

DEFECATQR FOR SUGAR-JUICES.

SPECIFICATION forming part of Letters Patent No. 658,602, dated September 25, 1900. Application filed May 21, 1900. Serial No.l7,439. (No model.)

To all whom it may concern:

Be it known that I, LEO VON TREsoKow, a German subject, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Heaters for Cane-Juice; and I do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in apparatus for heating cane or other saccharine juices prior to clarification; and it 0011- sists in certain novel features hereinafter described and claimed.

Reference is had to the accompanyingdrawings, wherein the same parts are indicated by the same letters and numerals of reference throughout the several views.

Figure 1 is a diagrammatic view showing my improved apparatus. Fig. 2 is an end View of the heater with the outer head removed. Fig. 3 is a view of the opposite end of the heater with the outer head removed,

and Fig. 4 shows a horizontal section along the line 4 4 of Figs. 2 and 3.

A represents a pipe for carrying the juice from the mill to the pump B, from which pump it is delivered by means of the pipe 0 to a chamber 1 in the end of the cylindrical heater D. This heater is provided with a number of pipes at for carrying the juice backward and forward under pressure at a considerable velocity, while the space between the pipes in the heater is filled with steam. I preferably arrange these pipes in groups, as shown. The juice entering the chamber 1 and passing through the six pipes opening thereinto enters the chamber 2 at the opposite end of the heater, where it returns through the other six pipes on the opposite side of said chamber, as indicated by the arrows, and thence it flows back to the chamber 3 at the opposite end, then across to the chamber 4, back to the chamber 5, and so on, all as indicated by the arrows, until it arrives at the chamber 17, whence it is carried by means of the pipe F.

The rectangular chambers l to 17, inclusive, are preferably closed by the outer heads D and D bolted onto the flanged cylinderheads D and D as by means of the bolts d, which heads, for convenience sake, are

hinged, as at (1 and provided with a handle,

Steam is supplied to the heater D through the pipe E which supplies the said steam at a reduced pressure from the reducing-valve E and the steam-pipeE, leading to the boi1- the pressure be too high it would require the parts to be stronger than would be economical in manufacture or repair.

D is a drain-pipe at the base of the heater to carry off the water condensed from the steam. Thejuice after passing through the heater is carried off by the pipe F, which is bent downward, as at F, into the tank H, which has a delivery-pipe I, controlled by the valve 1, and leading to the clarifiers or settling-tanks. (Not shown.) This tank H has also an overflow-pipe K, preferably controlled by relief-valve it, so as to normally shut out air and to be lifted by the pressure in the reservoir H when the latter becomes full. The tank H is intended merely as a reservoir to accommodate the liquid pumped through the heater while the valves to the various clarifiers are shut off, it not being the purpose to store up the juice in this tank for any length of time, but merely to pass it through from the heater to the clarifiers as quickly as possible. The heated juice passing to the clarifi'ers 0r settling-tanks and being at or near the boiling-point will settle rapidly, no blanket being formed, and is thus quickly put into condition for further concentration.

The tubes 61 in the heater D are preferably made of copper, so as to transmit the heat more rapidly and not to discolor the juice and because they can be more readily cleaned, and the juice being forced rapidly backward and forward through these tubes the tubes are secured thereby, and thus kept free from sediment, while any impurities in the juice are carried along to the clarifiers, where they may be removed. By having a large number of these tubes the juice is quickly brought to the desired temperature and the process of clarification is greatly accelerated. Moreover, the tubes and the entire apparatus being substantially air-tight the fermentation occurring in settling-tanks or in open-air tanks when not in use is obviated.

The various advantages of the herein-described construction will readily suggest themselves to any skilled sugar-maker, as they will consist in saving of steam, labor, and time, and in any sugar-house wit-h a limited clarifying or settling capacity the installation of above apparatus will enable the treatment of nearly double the amount of juice without doubling the number of clarifiers or settling-tanks.

It will be obvious that various changes might be made in the herein-described apparatns which may be used without departing from the spirit of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

An apparatus for heating cane-juice comprising a pump, a heater, provided with double heads with chambers contained between said heads, juice-pipes passing through said heater and connectingsaid chambers,a steampipe for supplying heat to the interior of said heater exterior to said juice-pipts, an airtight reservoir, a pipe connecting the heater with said reservoir, a delivery-pipe leading from said reservoir, an overflow-pipe from said reservoir, and a lifting relief-valve in said overflow-pipe and normally closing the same, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.

LEO VON TRESOKOVV.
